We are given that the absolute difference between the solutions is 1:
Can only be decreased by increasing the sample size. It cannot be used to determine exact individual figures, only a population range. Divide the entire first equation by 3 so
This is where the majority of the difficult questions live. Expect complex quadratic equations, non-linear systems, radical and rational equations, and advanced function notation.
